“…It is possible that the frequency of southern and southwestern cyclones increased. This is close to the period of active typhoons in South Sakhalin from 4030-3580 cal yr BP [75]. The warm subperiod from 4300-3550 cal yr BP in the southern part of the sea was associated with relatively strong intensity of the warm current [73].…”

“…The number of allochthonous lacustrine-rheophilic diatoms in the studied section on the Bolshoy Shantar Island confirms that recurrence of floods increased from 4670 to 4540 cal yr BP that was possibly connected with the intensification of typhoons although the storm activity in the archipelago was low. The period of paleo-typhoon activation in the south of Sakhalin Island occurred from 4640-4360 cal yr BP [75].…”

Allochthonous biofossil distribution in the blanket peat bog of Bolshoy Shantar Island was used to analyze atmospheric circulation anomalies in the north-western Okhotsk Sea over the last 12.6 ka. The main aim of this study was to determine periods of intensification of deep cyclones and extreme storms. The composition of bioaerosols is significantly influenced by atmospheric zonal and meridional transport anomalies associated with anomalies of the monsoon system of Northeast Asia, atmospheric fronts and cyclone trajectories. Marine diatoms enter the peatland from the sea during extreme storms and record the passage of sea cyclones in the autumn-winter, whereas the distribution of allochthonous pollen indicates the intensity of continental cyclones. We used Pinus pumila pollen as an indicator of heavy snowfalls and winter cyclone activity. Fifteen phases of extreme storms were identified. Changes in ice coverage also played an important role in bioaerosol emission. During cold periods, emissions of bioaerosols mainly occurred in the open sea, whereas during warm periods, emissions occurred near the coast. The recurrence and intensity of cyclones during the cold seasons depends on displacement of the Siberian High and Aleutian Low. Periods of continental cyclones intensified in spring-summer and coincided with periods of active winter cyclogenesis 2212.

Continued record of paleogeographic events in the Shantar islands since the end of the Pleistocene was restored on the basis of a multy-proxy study of the stratigraphy of the blanket peatland. Biostratigraphical studies included botanical, diatom and pollen analyses. The age-depth model was built using 7 radiocarbon dates. For the first time, data of the environment development were obtained for the coldest part of the Sea of Okhotsk. Synchronicity and metachronicity of paleoclimatic events with regional data and global changes have been established. The Younger Dryas on the Shantar islands was much colder than in other areas around the Sea of Okhotsk. The climate became more maritime after the isolation of the islands at the early-middle Holocene. The influence of the cold sea and the presence of drifting ice were one of the main factors, why the early and middle Holocene optimums were poorly manifested here, and also determined the specifics of climatic rhythm. Models explaining alternation of relatively warm and cold periods with different humidity are proposed. The age of periods with heavy snowfalls has been established, as evidenced by the change in the role of shrub pine in island vegetation. Phases of development of local swamp and zonal landscapes are highlighted. Spruce appeared on the area ~11410–10345 cal. yr. BP, when there was a landbridge, and spruce trees became common in the middle Holocene and especially at the boundary of the middle-late Holocene. One of the controlling factors for the development of swamp landscapes was thermokarst processes. Significant changes in the environment occurred in the Little Ice Age, the most severe conditions were ~500–260 cal. yr. BP. In the last 210 years, the most significant changes in landscapes have been associated with anthropogenic fires.
